A data relay system includes: a master 10 that functions as a master station of TDMA; slaves (21 to 23, 31 to 33, 41 to 43, 51 to 53, and 61 to 63) that function as slave stations of the TDMA; and REPs (20, 30, 40, 50, and 60) that relay communication between the master 10 and the slaves, function as slave stations in a higher-level TDMA system, and function as master stations in lower-level TDMA systems. The master 10 allocates, as a statically allocated time, an operating time once to each of the TDMA systems, sets, as a dynamically allocated time, a time obtained by excluding the statically allocated time from an allocated period, and allocates, based on communication states in the statically allocated time, the dynamically allocated time as operating times of the lower-level TDMA systems. |
